Objective To survey village doctors'knowledge,demand and behavior of health management,to provide scientific evidence for village people's health self-management.Methods Prepared a self-designed question-naire and make it completed by 106 village doctors chosen at random from 106 different villages in the eight towns in Guangzhou's two mountainous districts.Results The average age of the village doctors was(50.9 1 ±7.84)years, 36.79% of them had the ultimate diploma of a health technical school,and the average knowledge rate of health man-agement was 30.09%.There was remarkable difference among the 3 age groups which disclosed statistic value(χ2 =112.900,P =0.000).The 35-44 age group was the highest in the knowledge rate of health management (52.61%). The doctors with a ultimate technical diploma vary in the knowledge rate (the highest was 47.44%),which also had statistic value(χ2 =112.900,P =0.000).Only 2.83% of the village doctors believed that their health management skill can completely meetthe current demand and 3.77% can.18.87% believed that training about health management was very meaningfuland 25.47% meaningful.63.21% (most required by the health bureau) expected to receive training.16.98% didn't receive such training in the recent year because they thought it was un-necessary or not available.11.32% of the village doctors were willing to pay for the health management training,while 97.17% had never taken such training on their own expenses.Conclusion Village doctors are mostly elderly,low-educated,and insufficient in the professional knowledge of health management.Without the corresponding motivations and regulations,they are not enthusiastic about the training.It is suggested that the local authorities pay more attention to the buildup of the village health stations and improve the structure,knowledge,and earning of the village doctor group so as to ensure the effective health management service for the masses in villages.

The localization of adrenocorticotropin(ACTH),secretogranin Ⅱ in rat pituitary gland Was studied by using specific antisera in conjunction with double immunofluorescence staining techniques.Stainings with secretogranin Ⅱ serum showed intense cytoplasmic reaction in the anterior lobe of the pituitary gland.Double immunofluorescence staining was used to identify the cells that expressed secretogranin Ⅱ and ACTH.Confocal laser scanning microscopy revealed that ACTH existed simultaneouslywith secretogranin Ⅱ in quite a number of cells.The results indicate that secretogranin Ⅱ is expressed in corticotrophs of rat pituitary gland,its physiological role may be associated with the regulation of optimal pH in the secretory vesicles for the cleavage of ACTH from its precursor.

OBJECTIVETo explore the safety and efficacy of Shaobei injection in the management of I(-II( degree rectal prolapse.

METHODSA total of 80 patients eligible for the inclusion criteria were divided into 2 groups: 40 patients in the treatment group (treated with Shaobei injection) and 40 cases in the control group (treated with Xiaozhiling) respectively. The short-term efficacy was identified by the length of rectal prolapse and the depth of rectocele demonstrated by the defecography while the long-term efficacy was evaluated by the length of rectal prolapse. In addition, the safety was assessed by the occurrence of postoperative complications.

RESULTSThe variation of the lengths of rectal prolapse and the depth of rectocele demonstrated by the defecography at the sixth month follow up in the two groups did not reach significant difference (P>0.05). After 2 year follow up, 37 patients (92.5%) in the treatment group and 35 cases(87.5%) in the control group was cured. Therefore, there was no significant difference in the long term efficacy between the two groups (P>0.05). The adverse events in the therapy group(10%) was less than that in the control group (45%)(P<0.01).

CONCLUSIONSShaobei injection in the management of I(-II( degree rectal prolapse has a similar efficacy of short-term and long-term higher safety compared to Xiaozhiling injection.

Objective To investigate the impacts on inpatient costs of a hospital in Beijing as incurred by the reform of clinic-pharmacy-separation by means of DRGs. Methods As required by BJ-DRGs, we selected DRGs grouping information and medical record homepage information of the inpatients discharged from a tertiary hospital in Beijing from January to March in 2017 ( pre-reform group ) and that from May to July in 2017 ( the post-reform group ) . Then we compared the differences of inpatient costs before and after the reform, and the inpatient cost changes of the DRGs groups. Results The median of inpatient costs before the reform was 8751. 21 yuan, and that after the reform was 8522. 07 yuan, a difference without statistical significance (P>0. 05). Of the 104 DRGs studied, cost changes were found in 28 DRGs (P<0. 05), with increases in 19 DRGs and drops in 9 DRGs groups. Conclusions The reform, though without impact on the inpatient costs, changed the makeup of costs on the other hand, especially on HJ13 and BB25 DRGs groups, worthy of attention. A dynamic tuning mechanism is thus suggested for pricing of medical services, and a fine management suggested for the hospitals to curb unreasonable growth of costs.

Salt stress may cause primary osmotic stress and ion toxicity, as well as secondary oxidative stress and nutritional stress in plants, which hampers the agricultural production. Salt stress-responsive transcription factors can mitigate the damage of salt stress to plants through regulating the expression of downstream target genes. Based on the soil salinization and its damage to plants, and the central regulatory role of transcription factors in the plant salt stress-responsive signal transduction network, this review summarized the salt stress-responsive signal transduction pathways that the transcription factors are involved, and the application of salt stress-responsive transcription factors to enhance the salt tolerance of plants. We also reviewed the transcription factors-regulated complex downstream gene network which is formed by forming homo- or heterodimers between transcription factors and by forming complexes with regulatory proteins. This paper provides a theoretical basis for understanding the role of salt stress-responsive transcription factors in the salt stress regulatory network, which may facilitate the molecular breeding for improved stress resistance.

Exclusion criteria: lower urinary tract obstruction not caused by BPH, post-void residual urine volume(PVR) >250 ml; history of acute urinary retention in the last 3 months; prostate nodules and suspected prostate cancer were revealed by digital rectal examination and transrectal B-ultrasoundor; prostate-specific antigen (PSA)≥10 ng/ml; neurogenic bladder, perivous history of bladder, prostate, or urethra operations; suffering from serious heart, lung, liver, kidney and other diseases. The patients in the experimental group were orally treated with black tomato concentrated sauce(30 g/once, 3 times/day). The patients in the placebo group were orally administrated with placebo. In the positive control group, the patients with PV≤30ml were orally treated with tamsulosin(0.2mg/once, 1 time/day), the patients with PV>30ml were orally administrated with tamsulosin and finasteride(5 mg/once, 1 time/day). All enrolled patients were treated for 3 months. At the end of third month, the IPSS, QOL, PV, PVR, Q max, average urinary flow rate(Q ave), total PSA(tPSA), free PSA (fPSA), testosterone(TST) and the incidence of adverse reaction were assessed. Results:128 of 150 cases, including 52 cases in experimental group, 36 cases in placebo group and 40 cases in positive control group, completed the study, the rest was excluded due to not take medication regularly and fail to follow-up. There were no significant differences in baseline parameters among experimental group, placebo group and positive control group ( P>0.05) in age[(63.21±8.61) vs.(62.36±6.32) vs. (63.94±7.78)years old], body mass index[(23.74±3.17) vs. (23.94±3.09) vs. (24.26±2.91)kg/m 2], IPSS[(17.5±6.6) vs. (15.4±5.8) vs. (17.9±6.8)], QOL[4.0(3.0, 4.0) vs. 4.0(3.0, 4.5) vs. 4.0(3.0, 5.0)], Q max [(8.60±3.04) vs. (9.13±2.92) vs. (9.58±3.26) ml/s], Q ave[(4.39±1.69) vs. (4.66±1.76) vs. (4.88±1.60)ml/s], PV [32.00(25.55, 45.40)vs. 30.00(24.45, 38.35)vs. 34.80(27.65, 56.65)ml], PVR[23.50(8.25, 45.75) vs.5.50(0, 47.75) vs. 29.00(0, 84.00)ml], tPSA [1.53(0.89, 3.00) vs. 1.23(0.69, 1.98) vs. 2.23(0.90, 4.15)ng/ml], fPSA [0.37(0.28, 0.76) vs. 0.37(0.22, 0.52) vs. 0.54(0.30, 0.97) ng/ml] and TST[(443.64±156.32) vs. (493.97±176.16) vs. (450.89±135.08)ng/dl]. After 3 months of treatment, the IPSS in experimental group was(9.9±5.7), QOL score 2.0(2.0, 3.0), Q max(11.78±5.24)ml/s, Q ave(5.86±3.00)ml/s, tPSA 1.64(0.96, 3.32)ng/ml and TST (475.91±177.33)ng/dl, which were significantly different compared with pre-treatment( P<0.05). In positive control group, IPSS was (9.0±6.2), QOL 2.0(2.0, 3.0), Q max(11.73±4.50)ml/s, Q ave(6.11±2.53)ml/s, tPSA 1.57(0.80, 3.09)ng/ml, fPSA 0.37(0.24, 0.63)ng/ml and TST (526.11±126.88)ng/dl, which were statistically different compared with pre-treatment( P<0.01). However, there were no significant differences in all the above indexes in placebo control group compared with the baseline( P>0.05). The numerical changes of IPSS, QOL, Q maxand Q ave between experimental group and placebo group had statistically significant differences ( P<0.05). The changes of IPSS, QOL, Q max, Q ave, PV, tPSA, fPSA and TST between positive control group and placebo group had significant differences ( P<0.05). The changes of PV, tPSA and fPSA between positive control group and experimental group had statistically significant differences ( P<0.05). The incidence of adverse reactions was 5.77% (3/52, including 1 headache and 2 stomach discomfort) in experimental group, 5.56% (2/36, including 1 headache and 1 stomach discomfort) in placebo group, and 10.00%(4/40, including 1 dizzy, 1 nasal obstruction and 2 erectile dysfunction) in positive control group. And there was no statistical difference in the incidence of adverse reactions among three groups ( P>0.05). Conclusions:Black tomato concentrated sauce shows an excellent effect on patients with LUTS/BPH, and improves the quality of life with few adverse events.

To prepare polyclonal antibodies (PcAb) against UspA1 of Moraxella catarrhalis (Mc), we used bioinformatic analysis to determine the surface exposed region in this protein that holds the antigen epitopes. Then the corresponding coding sequences for this fragment was artificially synthesized according to the codon usage of Escherichia coli. The gene fragment was then subcloned into the prokaryotic expression vector pET-28a(+) and expressed in E. coli rosseta (DE3), and then the recombinant UspA1-His proteins were purified. Two New Zealand white rabbits were immunized with this protein to prepare antiserum. The resulting PcAb was then purified from the antiserum with Protein A affinity column. The results of fluorescence antibody assay, enzyme linked immunosorbent assay and Western blotting analysis showed that the PcAb could specifically recognize the surface exposed region of UspA1 on Mc. The preparation of the PcAb laid a foundation of further development of rapid detection technique for M. catarrhalis.
